Fantasy put out this 12" in the 80s, with the disco/boogie track 'don't know to say' (produced by George Duke) on the a-side. The track is pretty decent, but the real action is on the b-side, where Fantasy put an extended version of the '76 track 'Rock Creek Park' on. Rock Creek Park is a heavy jazz funk masterpiece, that was way ahead of his time. The great bassline, heavy drums and sweet female vocals make this essential for dj's. The track was produced by Donald Byrd and I'm pretty sure that the Mizell Bros. where in the studio that day.
